Sentry MidRange

MidRange

Dimensions: 1.52″ x 0.67″ x 0.22″ (bare tag) | 2.50″ x 0.69″ x 0.25″ (with cover)

Tag overview

Product Number: AST1-174-0300 (bare tag) | AST1-174-2300 (with cover)

Improvements in RF chip design, and Vizinex’s expertise at matching the new chips to highly efficient antennae, are improving the performance and reducing and cost of RFID. The Midrange is the third generation of Vizinex’s highly successful tag for tracking larger metal assets. The latest generation is 30% smaller than the original VX Mid, but it provides a 30% better range and broader frequency response at a price that is 25% lower.

The new tag has a relatively small footprint of 39mm x 17mm. Despite this small package, it provides a read range of 33’ (10m) when mounted on metal.

The smaller footprint and lower cost of the latest tag will enable the cost-effective tagging of a wide range of metal assets from reusable containers to oil field assets to construction equipment. The optional cover provides extra protection for the RF device and the flexibility to use bolts, rivets or zip-ties for attachment.

The Midrange is also available in a multi-surface version that has a read range of 25’ (7.5m) on metal and 21’ (6.5m) off metal. All other specifications for the multi-surface version are the same as those for the on-metal version.
